Requirements
Cable
Terminals
Terminals shall be sized for the correct current capacity of the circuit as stated by the manufacturer.
Terminals shall be plated with tin, nickel, gold, etc. Mating terminals shall be plated with the same material. Gold plated
terminals shall be required in 5 volt dry circuits. Beryllium Copper or equivalent should be used as a base material.
Ring Terminals
Terminals such as ring, bullet, spade, ect., shall be sized for the correct current capacity of the circuit as stated by the
manufacturer. Terminals shall be plated and non-insulated. Sleeves shall be insulated with a double wall shrink tubing.
Convoluted Conduit
Convoluted conduit must have a maximum operating temperature of at least 300°F (149°C).
Braided Loom (Mesh)
Coverage: A minimum of 10, maximum of 12 picks per inch. The braid shall be woven so as to produce a tight non-slip
covering over the cables. The braid shall be heat-sealed to prevent unraveling. Braid must have a minimum service tem-
perature of 280°F (138°C).
Insulating Sleeves
Sleeves shall be constructed of a heat shrinkable, irradiated, adhesive lined, semi-rigid polyolefin. The color shall be
black. Typical shrinkage shall be 50% in diameter when exposed to heat (300°F) (150°C).
Tape
Adhesive tape for harness forming and spot taping shall be polyvinyl chloride (PVC). The tape shall have a pressure
sensitive adhesive coating on one side.
Assembly Procedures
Crimping
The crimp shall be applied with a tool specified by the manufacturer of the terminal.
Terminals shall be applied according to terminal manufacturer’s specifications.
Stripping
An allowable maximum of 2 strands may be cut on 16 gauge or larger, 1 strand on 18 gauge, and no strands on 20
gauge in the crimp area.
